Abstract

Electronic spectra of nine title compounds were measured and the substituent effect on λmax and εmax has been discussed. Competitive electron withdrawing by both the nitro groups in a molecule and a disturbance of mutual electronic interaction of substituent by a stеric ortho effect were found. The preparation of five new 2-(N-alkyl-N-nitrosoamino)-4- and 6-methyl-5-nitro- and 2-(N-methyl-N-nitrosoamino)-6-methyl-3-пitropyridiпes is described.
